Definitions
- the invention relates to a rear wheel suspension for motor vehicles, in particular Passenger cars, with a trailing arm and at least two Wishbones per wheel carrier, which also has a rear axle gearbox supporting rear axle are hinged to which the vehicle body is elastically connected.
- the technical environment is based on the EP 0 193 090 B1.
- a rear suspension according to the preamble of claim 1 has fundamentally proven, especially since across the essentially transverse to the longitudinal axis of the vehicle trailing arms essentially extending in the vehicle longitudinal direction for the two wheel carriers with respect to their suspension favorable driving dynamics conditions can be achieved.
- a rear axle beam on which at least the wishbones are articulated is an advantageous one Vibration and structure-borne noise decoupling are given.
- a rear axle gear i.e. it is a powered one Rear axle or driven wheels, with a required differential or rear axle transmission advantageously also carried by the rear axle carrier becomes.
- the rear axle beam consists of two separate carrier units, one of which is the left one Wheel carrier and the other is assigned to the right wheel carrier and between and on which the rear axle gear is suspended.
- Beneficial Training and further education are included in the subclaims.
- the one known in the prior art self-contained frame forming rear axle support which in the known State of the art on four partially elastic support points with the vehicle body or connected to the underbody of the vehicle body, in two independent carrier units divided.
- Each carrier unit is independent attached to the vehicle body and is with the other carrier unit practically only about the on these preferably left and right respectively two struts aligned essentially transversely to the longitudinal axis of the vehicle connected rear axle gear connected.
- This allows a cheap one Vibration decoupling.
- the reference number 1 denotes the longitudinal axis of a passenger car whose rear axle is driven, for which purpose a rear axle gear 2 (with an integrated differential) is provided. Shown are the two wheel carriers 3 arranged symmetrically to the longitudinal axis 1 of the vehicle, which are of course each connected to the assigned output of the rear axle gear 2 via a drive shaft (not shown).
- each wheel carrier 3 In addition to a trailing arm 4, which in is aligned substantially parallel to the longitudinal axis 1 of the vehicle, are each wheel carrier 3 at least two extending essentially transversely to the longitudinal axis 1 of the vehicle Wishbones 5 are provided, of which only for the sake of simplicity one per wheel carrier 3 is shown. On this wishbone shown 5 is also based - as can be seen - essentially in the vertical direction and thus spring-damper unit extending perpendicular to the plane of the drawing 6, on the opposite end of which is not Vehicle structure shown supports.
- the two wishbones 5 articulated to each wheel carrier 3 are included their opposite end also articulated on each wheel carrier 3 associated carrier unit 7 attached. So the two of them the longitudinal axis 1 support units designed in mirror image to one another 7 are approximately triangular, as can be seen, i.e. they exist suitable here from three each - and here approximately in the form of the letter "A" - composite profile struts or the like
- Each carrier unit 7 has three bearing points 8, which are preferably close to the Corner points of the essentially triangular support unit 7 are located statically determined tied to the vehicle body, preferably over Rubber bearings or the like.
- the two carrier units 7 carry between them in addition, the rear axle 2, each over two essentially Struts 9a, 9b aligned transversely to the longitudinal axis 1 of the vehicle.
- the rear axle gear 2 can hereby be seen over a relatively broad base to the two independent carrier units 7, which in their entirety can be referred to as a rear axle carrier, coupled, whereby this coupling via the struts 9a, 9b or via corresponding joints can be sufficiently elastic.
- this is the rear axle gear 2 and thus also the one connected to it Vehicle drive train additionally and therefore particularly effective from vehicle Structure decoupled.
